I just checked my AU Versions, and what you have available in the downloads/Updates area for some of my Arturia software. It does not jive with the table you link to. It would help tremendously, if that table included version numbers, next to each product - so I could seek out these versions. Here are the software, that I specifically do NOT see 64 bit AU versions for.. Can you tell me where I can download the 64 bit versions that are on the Arturia table in the link you provided?

Maybe my question doesn't translate well? Specifically - I am asking.. Where can I download the 64 bit versions of AU versions of: ARP2600, Prophet, and Wurlitzer software? The article you linked says that they are available... but I cannot find them to download.
